25kva single-phase oil-filled pole-mounted distribution transformers 13.8KV 34.5KV To 240V
WINLEY’s single-phase, oil-filled, pole-mounted distribution transformers are designed for servicing residential overhead distribution loads. They are also suitable for light commercial loads, industrial lighting and diversified power applications. These transformers are designed for the application conditions normally encountered on electric utility power distribution systems. Types CSP, CP, SP and S are all available. ISO 9001: 2008 Certified
Structural Features
1. The tank lids have high-voltage porcelain bushings that come with ring terminals, which can accommodate either aluminum or copper cables.
2. The circular sewing structure of the tank cover ensures even stress distribution and reliable sealing.
3. The ring bolts on the tank wall serve as the low-voltage bushing and terminal and are tin-plated.
4. This item comes with a pressure relief valve that is capable of self-sealing.
5. According to ANSI standards, the transformer's suspension hooks at the top and bottom comply.
6. The ground terminal on the tank is a ring bolt ground terminal.
